A 42-year-old woman with acute myeloid leukemia undergoing intensive chemotherapy (absolute neutrophil count 80/μL) presents with persistent fever unresponsive to broad-spectrum antibiotics for 7 days.

High-resolution CT confirms the halo sign. Sputum culture grows Aspergillus fumigatus. What is the most likely diagnosis?
